The proposed nation-wide survey follows on the results of a previous study done by the Nanyang Technological University (NTU) with partners TUMCREATE and Surbana Jurong that indicate a potential geothermal resource at a site near the Sembawang hot spring. Based on the study, there is potential of heat from 4 to 5 kilometers depth to be harnessed for power generation, with temperatures at depth estimated to be as high 200 degrees Celsius.
The EMA had also previously issued an RFI to identify possible approaches, methodologies, and execution details for carrying out a geophysical investigation to ascertain Singapore’s geothermal potential and identify suitable deployment locations.
The comprehensive study under the RFP will provide additional data to assess geothermal energy as a potential source of renewable energy, and identify suitable locations for the potential deployment of geothermal power plants in Singapore. The data and information availed through the study will also be used to assess the potential for subsurface geologic carbon sequestration in Singapore.
As a small, resource-constrained country, Singapore has limited renewable energy options and imports almost all its energy needs. EMA is thus exploring indigenous energy options other than solar to further diversify and decarbonize Singapore’s energy sources to support Singapore’s international climate commitment to achieve net zero emissions by 2050, while also improving the country’s energy resilience.
